I loved staying at Serene suites, very private and the room is nice for the price paid. Things to note, it is a good 12-15 minute walk to the MRT and not the most walkable path either. Also, this room is next to a bar that has karaoke nights or singers coming. All that has to be done is to close the window and you barely hear it. Lastly, might be because I stayed for a month but I had to buy a lot of the amenities, which brought the price up for me. Things to consider before booking, but overall, it is a great place to be and the MRT is 2 stations from Sukhumvit MRT and Asok BTS. You are also one MRT station away from Lumphini and Benchakitti Parks.
